Which of the sets of ordered pairs represents a function?

IgorC [24]

Answer:

Neither set A nor set B represents a function.

Step-by-step explanation:

According to the definition of a function, for each input there exists a unique output. In other word for each value of x there exists unique value of y.

In set A we have four ordered pair (-4,5),(1,-1),(2,-2) and (2,3).

It means for x=2, we have two values of y, i.e., -2 and 3.

Since for a single value of x there exist more than one value of y, therefore set A is not a function.

In set B we have four ordered pair (2,2),(3,-2),(9,3) and (9,-3).

It means for x=9, we have two values of y, i.e., -3 and 3.

Since for a single value of x there exist more than one value of y, therefore set B is not a function.

What is the surface area of this right rectangular prism? Enter your answer as a

mixas84 [53]

You will find all of the surface area of all of the sides and add them together to find the surface area of the retangular prisim. So, what I would do is the front and back are both 54, so 108. The sides are 27, so 54. The top and bottom are 18, so 36. Add them together, and you will get 198. I hope this helps.

The picture below shows a right-triangle-shaped charging stand for a gaming system:

Setler79 [48]

This question is incomplete because it lacks the diagram of the right angles shaped charging stand.

Find attached to this answer, the appropriate diagram.

Answer:

3(tan 50°)

Step-by-step explanation:

To solve this question, we would be using the Trigonometric function called Tangent.

tan θ = opposite side/ adjacent side

θ = 50°

Opposite side (Height)= Side AC = Unknown

Adjacent side = Side BC = 3 inches

Hence,

tan 50° = Side AC/ Side BC

tan 50° = Side AC / 3

Cross multiply

tan 50° × 3 = Side AC

3(tan 50°) = Side AC

Therefore, the expression shows the height, AC, of the charging stand is

3(tan 50°).
